题目内容

【题目】地理科学探索是正确认识地理现象和事物的途径之一,一般包括“观察发现﹣大胆假设﹣寻找证据(实验验证)”等过程。下列地理事件或理论最能体现上述探索过程的是(
A.斯科特南极探险
B.魏格纳的大陆漂移说
C.麦哲伦环球航行
D.中国发射北斗导航卫星

【答案】B
【解析】大陆漂移假说是20世纪初魏格纳提出的。大陆漂移假说认为,地球上原先只有一块叫“泛大陆”的庞大陆地,被叫做“泛大洋”的广袤海洋所包围。大约两亿年前,泛大陆开始破裂,碎块像浮在水上的冰块一样向外越漂越远。距今大约两三百万年前,形成现在七大洲,四大洋的基本面貌。魏格纳从地图观察大西洋两岸凹凸吻合,由此猜测这里很早以前曾经连在一起,创立了大陆漂移说,并实地考察,寻找证据加以印证,最能体现“观察发现﹣大胆假设﹣寻找证据(实验验证)”的探索过程。 故选B
